This part of IEC 62722 specifies the performance requirements for LED luminaires, together with the test methods and conditions. It applies to LED luminaires for general lighting purposes. Semi-luminaires are not covered under the scope of this document. For some types of luminaires (e.g. decorative/household) the provision of performance data under the scope of this document is not appropriate. The following types of LED luminaires are distinguished. Type A Luminaires using LED modules where evidence of compliance with IEC 62717 is given. Type B Luminaires using LED modules where no evidence of compliance with IEC 62717 is given. Luminaires using a LED lamp are covered in IEC 62722-1 and not by this document. The requirements of this document only relate to type testing. This document covers LED luminaires using LED modules, based on inorganic LED technology that produces white light. It does not cover luminaires using light sources based on OLED technology (organic LED technology). Life time of LED luminaires is in most cases much longer than the practical test times. Consequently, verification of manufacturer s life time claims is out of the scope of this document. Instead of life time validation, this document has opted for lumen maintenance categories at a defined finite test time. Therefore, the category number does not imply a prediction of achievable life time. The categories are lumen-depreciation character categories showing behaviour in agreement with manufacturer s information which is provided before the test is started.
